Last June, horrified by what they were reading in the news, bloggers across the UK came together to highlight the atrocities taking place in Syria. Last September, we united again; shocked that nothing had changed, appalled by the torture and terror being suffered by Syrian women and children.

Today, sadly, we have to do it once more.

On Friday, it will be two years since the violence in Syria began. Just think about that – two whole years – reflect on what has happened in your own life in that time, and then take just a minute to imagine how life has been for the people of Syria.

The UN has now announced that the number of refugees fleeing Syria in that time is now over 1 million, and over half of those are children. This short video from Cat Carter – working for Save the Children near the Syrian border – gives you an insight into the kind of story that every single one of those refugees has to tell.

So far, we have not been able to fix things.

Our voices have not been loud enough.

The pressure on politicians to act has not been strong enough.

It is time for that to change.

This can’t go on.

Tomorrow – Thursday March 14th – Save the Children launches its Global Vigil for Syria.

As ever, there are a variety of ways you can get involved, depending on how much time you want to commit.

It can be as easy as sending one tweet, or sharing one Facebook status, like this one.

Join me & @savechildrenuk in a Global Vigil demanding world leaders unite to help save Syria’s children http://bit.ly/XnyRqD #SyriaCrisis

Or you can sign up to the vigil on Save the Children’s website here. They will collate all the messages, and release them online in a co-ordinated wave across the world’s time zones.

If you want to donate to the campaign, to help provide much needed support to efforts on the ground, then you can do so here.

And if you want to write a blog post yourself you can use the digital kit that Save the Children have put together.

This time – if there are enough of us, if we shout loudly enough, if we put on enough pressure – we can make a difference.
